| Abstract: | In this paper is given an overall review on the recent advances in research on genetic improvement and breeding strategies of spruce in the world.The cause of "seed orchard crisis" was also discussed.The research methods,techniques,production scales,application prospects and possible drawbacks of clonal forestry in Norway spruce in Germany,Sweden,Denmark,Norway and Finland were presented,the genetic improvement of spruce in the world has been developing rapidly with high efficiency at low cost.On the basis of comparing the recent status in this field in Sichuan with those mentioned above in foreigns,sichuan's research efforts are recommended to promote the development of tree improvemental works in the future. |
